Pamela bought an electric drill at 85% of the regular price. She paid 32.89 for the drill. What is the regular price?

Answers

Answer 1

Answer:

Answer: $ 38.69

Step-by-step explanation:

Let x be the regular price of an electric drill.

Given : Pamela bought an electric drill at 85% of the regular price.

i.e. the paid price for electric drill = $0.85x$

Also, she paid 32.89 for the drill.

Then , we have the following equation :-

$0.85x=32.89$

Divide 0.85 on both the sides , we get

$x=(32.89)/(0.85)\approx38.69$

Hence, the regular price of electric drill = $ 38.69

Answer 2

Answer: Let x represent the regular price.
$0.85 * x = 32.89$
$x = (32.89)/(0.85) = 38.69$
x = $38.69 so the original price is 38.69 dollars

1) Mr. Adams had 24 guests at his house for a party. Each guest brought one item. - One-third of the guests brought drinks.

- One-fourth of the guests brought a dessert.

- The rest of the guests brought chips.

How many guests brought chips?

Answers

10 guests brought chips. To find the total number of guests who brought each item, all you need to do is divide 24 by the number in the fractions denominator. Then, add your answers and subtract them from 24 to get the total number of guests who brought chips.

24 / 3 = 8
8 guests brought drinks.

24 / 4 = 6
6 guests brought desserts.

6 + 8 = 14
24 - 14 = 10
10 guests brought chips.
